A controversial artifact from the Suffolk County Historical Society permanent collection believed by some to have been made by Captain John Hulbert of Bridgehampton and carried by him and his Third Regiment of New York militiamen from Fort Ticonderoga to Philadelphia in 1775 where, after having been seen by representatives at the Continental Congress, it might have influenced the design of the first American flag.
 
The flag has been examined by a number of experts who remain divided over the oral tradition of the flag's origins. The Hulbert Flag remains one of the best known and most discussed artifacts in the society's collections. Note the six-pointed stars are arranged in the cross of St. Andrew.

Along Montauk Highway, in the middle of the hamlet of Water Mill, you will notice a historic windmill on the south side of the road. 

Though an earlier mill once stood at the site, a three day blizzard destroyed it in December 1811. The current windmill was built on Hog Neck (now the Village of North Haven) in 1800. To replace the destoryed one, James Corwith purchased the new windmill in 1813, dismantled it, and moved the sections by oxen to the commons. In 1860 he purchased the common’s land from the Town Trustees.

He would grind grain until his death in 1868 when his son Samuel took over the ownership of the windmill, along with that of the Corwith General Store across the highway. The mill ceased grinding about 1887 when a large summer home to the west blocked prevailing winds, and a flour factory in Sag Harbor began producing cheaper, finer, and whiter flour. 

The Corwith Windmill then changed hands five times as it was sold to various owners of the summer house built to the west of the mill. Every time a summer resident sold their house lot, they also sold the mill back to the Corwith family, who sold it to the next homeowner. It was these wealthy second-home owners who kept the mill in good repair even installed a stone foundation to replace the stacked boulders it previously sat on. Today the mill is owned and maintained by the Water Mill Village Improvement Association, a local non-profit organization.

The Corwith Windmill is the smallest, second oldest, and has the most primitive machinery of the 11 surviving windmills on the East End. It is a good example of 17th and 18th century mills of Long Island and New England.

It is sometimes called a smock mill because its tapered lower shape is similar to a smock. The cap of the mill, where the wind sails are located, sits on a heavily greased wooden ring or “dead” curb at the top of the mill. The miller rotates the cap and sails into the prevailing wind by pushing the 36 foot tail pole. All other existing windmills in the area have rollers on the curb and had a fantail device installed that automatically turned the cap into the wind.

Surfrider Foundation’s Eastern Long Island chapter is joining the worldwide movement to get rid of plastic straws. At one beach cleanup in Greenport, the Eastern Long Island Chapter removed 922 straws from the beach. The goal of this program is to reduce the number of plastic straws used in restaurants in Eastern Long Island.
 
PARTICIPATING RESTAURANTS WILL PLEDGE TO: 
1. Go completely Strawless      or
2. Provide biodegradable (paper, bamboo) straws only upon request     or
3. Provide reusable alternatives to plastic (stainless steel)
Is your restaurant ready? Make the Pledge Here. 

HERE’S THE SURFRIDER PLAN:

• Educate the public about the negative effects of plastic straws
• Collect data about number of plastic straws being used on the East End, price per straw, and distribution company
• Host a screening of the film “Straws“
• Do market research and provide price alternatives to interested restaurants, proving that using fewer single use straws can be cost effective
• Team up with local schools and ask students for help spreading the word
• Sign restaurants up to make the pledge to be a part of the 2018 Strawless Summer
• Launch a kick off party at one of our participating restaurants
• Celebrating the restaurants who choose to join by providing them with a Strawless Summer 2018 window decal, including them on our website’s interactive map below, and through social media.

Restaurants:
​1.  Take this Survey.  This survey will help us collect information about the use of plastic straws with the ultimate goal of making alternatives more approachable for restaurant owners. Please help the chapter out by filling out this quick survey! We respect your Privacy. Answers given will not be shared.
2. Sign this Petition asking East End restaurant supplier to provide alternatives to plastic straws.
3. Make the Pledge Here  if your restaurant is ready to commit.
Consumers:You can help us with our program as you go throughout your day- to- day life.. Ask yourself if you really need a straw, and start to notice how often you automatically get a straw. Remind your server,  “No straw, Please!” 
Volunteer by helping us approach restaurants and gather information. Ask the manager or owner to take our survey (PDF Version / Online Version), and help us figure out what it would take for them to go strawless.

The historic Cedar Point Lighthouse was built in 1839 to guide mariners entering Sag Harbor when the town was the center of whaling and fishing and a magnet for transportation vessels. The structure was replaced in 1868.

Since the Cedar Island Lighthouse was decommissioned in 1934, it has passed through private hands until it became part of Suffolk County’s Cedar Point Park in the late 1960’s.
 
The lighthouse was originally built on a three-acre island. The hurricane of 1938 created a sandbar connecting Cedar Island to the mainland of East Hampton which is now known as Cedar Point.
 
Vandalism and weather have taken their toll on the Cedar Island Lighthouse. Its construction of granite from New England has withstood the test of time, but in 1974 a fire gutted the interior of the Lighthouse.
 
The Long Island chapter of the United States Lighthouse Society has been authorized by Suffolk County Parks to restore and “Relight the Lighthouse”.
 
Today the Lighthouse grounds are under the care of the Suffolk County Parks Commission.
 
The 607-acre Cedar Point Park, with commanding views of Gardiner's Bay, offers individual and organized group camping areas. Picnic areas, boat rentals, nature trails, vehicular access to the outer beach (with permit only), surfcasting for bass and bluefish, bicycling and rowboat rentals.
 
Located at 5 Cedar Point Rd, East Hampton, NY 11937
call 631.852.7620 for info.
 
How to get there:
Take Montauk Highway, 27east, to Stephen Hands Path in East Hampton. Turn north and continue to Old Northwest Road. Turn right on to Northwest Road. Bear left and continue to Alewive Brook Road. The park entrance is nearly 100 yards down the road.
